Are you assuming that the APN has exactly one globally routable IPv4 address? If so, it can only own one 6to4 /48 prefix, i.e. 64k /64s as you say. But if the APN has 2 IPv4 addresses, it can have two 6to4 prefixes, etc. What is the realistic requirement for the number of primary PDP contexts per APN?
